  The objective was to assess the heterotic relationship among nine maize inbreds derived from temperate, subtropical and tropical material. The nine inbreds and their diallel crosses excluding reciprocals were evaluated for eleven biometric traits viz., days to pollen shedding, plant height, leaves plant-1, leaf area, ears plant-1, ear weight, grain moisture at harvest, kernel rows ear-1, kernels row-1, 100-kernel weight and grain yield. High heterotic effects were observed for plant height, ears plant-1, ear weight, kernels row-1, 100-kernel weight and grain yield. Average MP and HP heterosis was 17.2 and 2.8%, respectively, for grain yield. Hybrid NCML-1082xNCML-1083 was the highest yielding with 82.6 and 74.5% heterosis relative to MP and HP, respectively. Subtropical and tropical heterotic groups were distinct for high grain yield in this study. Tropical lines also gave some reasonably good heterosis with sub-tropical material for other plant characters and also within its own origin (intra-origin) in certain combinations.

  Six maize genotypes were evaluated in National Uniform Maize Yield Trials across six contrasting locations having different agro-climatic conditions. Pooled analysis of variance for grain yield indicated significant differences for genotypes across the environments, environment across genotypes and their interactions. These significant interactions indicated uneven performance of the genotypes across the environments and years. In stability analysis, all the parameters applied proved two genotypes as the most stable across the environments. These genotypes gave the highest grain yield and were also earlier in maturity. One genotype showed fitness for favourable environments and two for poor yielding environments.

  Maize, the leading world cereal, offers the greatest potential for increasing food productivity in countries like Pakistan. The average yield in Pakistan is low compared to the world average. An effective short term strategy to improve maize productivity is to replace the local low yielding varieties and landraces with high yielding hybrids. However, mainly due to very high cost of the imported hybrid seed in Pakistan, the hybrid technology has not been adopted on larger scales. Currently, 25% of the maize area is under hybrids in Pakistan. Therefore, there is a great need to develop, popularize and adopt maize hybrids with indigenous blood. Indigenous hybrids for agro-ecological zones not attended by the private multinational have been developed at National Agricultural Research Centre and tested in the respective ecologies. Six selected indigenous hybrids (NARC-2701, NARC-2702, NARC-2703, NARC-2704, NARC-2705, NARC-2707) were evaluated at two location during spring season. Four leading commercial hybrids (Bemisal-202, 3335, 2303 and 6525 from Engro, Pioneer, Rafhan and Monsanto) were used as checks for comparison. Some of the indigenously developed hybrids (NARC-2702, NARC-2703, NARC-2704, NARC- 2705) performed better than, or as good as their exotic counterparts. These hybrids exhibited desired idiotypes as indicated by plant and ear heights. The indigenous hybrids were earlier in maturity than the commercial checks. These results clearly indicate the superiority and suitability of locally developed (indigenous) maize hybrids for spring planting in Pakistan.

  Maize, the leading world cereal is the third most important cereal in Pakistan following Wheat and Rice. Although, its direct utilization as human food (25%) is declining, its industrial (29%) and feed (35%) use is increasing. The normal maize lacks two of six essential amino acids, that is, lysine and tryptophan. The Quality Protein Maize (QPM) with higher protein and much higher tryptophan and lysine content has been shown to improve animal and human health. Keeping these facts in mind, a number of QPM hybrids have been constituted at National Agricultural Research Centre (NARC), Islamabad from the temperate and subtropical originated lines from CIMMYT. The data presented in this study indicate that 4 selected QPM hybrids performed well in comparison to commercial maize hybrids. The results on yield and other agronomic characteristics along with lysine content of QPM hybrids are presented and discussed. With high yield and better quality, the new QPM hybrids can lead to food, feed and nutritional security and help to alleviate poverty among resource-poor farmers of the country.
